An illuminated ball may be used to play games in the water. An illuminated ball may include a hollow, spherical shell. A translucent light housing may be coupled to the shell. A light emitting device may be within the translucent housing. A battery housing coupled to the light emitting device. At least one battery may be within the battery housing. A circuit board may be coupled to the battery housing. Four conductors may be coupled to the circuit board, wherein two of the four conductors are coupled to the light emitting device and another two of the four conductors are coupled to at least two water contacts. The at least two water contacts are located on an outside of the illuminated ball, wherein on exposure to water, the at least two water contacts are electrically connected causing the light emitting device to emit light.
